    It’s easy to overlook with the omnipresent internet, but self-hosting doesn’t require internet. You could host for your fellow students on the local network. If that’s also against the Wifi rules you can either ignore that stupid rule or set up your own god damn wifi with hostapd on your machine and let students connect directly to it. It’s probably best to use a machine dedicated to the task for security reasons as you wouldn’t want curious students to accidentally erase your homework. I wouldn’t use containers or VMs for any of this, I’d just use bare metal like in the good ol’ days. You could also, without having to worry, give people shell accounts because it’s a closed network. The options are endless without all the worries of hosting on the internet.

    It seems that we focus our interest in two different parts of the problem.

    Finding the most optimal way to classify which images are best compressed in bulk is an interesting problem in itself. In this particular problem the person asking it had already picked out similar images by hand and they can be identified by their timestamp for optimizing a comparison of similarity. What I wanted to find out was how well the similar images can be compressed with various methods and codecs with minimal loss of quality. My goal was not to use it as a method to classify the images. It was simply to examine how well the compression stage would work with various methods.

    I was not talking about classification. What I was talking about was a simple probe at how well a collage of similar images compares in compressed size to the images individually. The hypothesis is that a compression codec would compress images with similar colordistribution in a spritesheet better than if it encode each image individually. I don’t know, the savings might be neglible, but I’d assume that there was something to gain at least for some compression codecs. I doubt doing deduplication post compression has much to gain.

    I think you’re overthinking the classification task. These images are very similar and I think comparing the color distribution would be adequate. It would of course be interesting to compare the different methods :)

    I agree and the requirement for an exact placement of attribution is not very friendly to derivate works either. I don’t think that section 7 of AGPL allow adding anything other than the exact terms in section 7 and it has a clause that allow removing non-permissive additions to the AGPL, but I’ve sent an e-mail to FSF asking what their position is. I would be very concerned picking AGPL as a license for my projects, if section 7 allow adding clauses like that. Anyhow the clauses were added in this commit, so anything prior to 7.3.0 is normal AGPL.

    There is no free and open source version of Only Office. It fakes that it is licensed with AGPL, but they have added the following to the license, which in effect completely forbid you to redistribute it. It can be said to be Source Available.

    The interactive user interfaces in modified source and object code versions of ONLYOFFICE must display Appropriate Legal Notices, as required under Section 5 of the GNU AGPL version 3.

    Pursuant to Section 7 § 3(b) of the GNU AGPL you must retain the original ONLYOFFICE logo in the upper left corner of the user interface when distributing the software.

    Pursuant to Section 7 § 3(e) we decline to grant you any rights under trademark law for use of our trademarks.

    You need to use a dmix PCM for you card as output.

    If you type aplay -L | grep dmix it’ll show you a list of dmix devices. You can set one as the default if you create a file named .asoundrc in your homefolder with the content:

    pcm.!default {
  type plug
  slave.pcm "dmix:CARD=Set,DEV=0"
}

    You of course replace the value of slave.pcm with your desired card name. I just gave one of mine as an example. The above default configuration also takes care of automatic conversion, via the plug pcm, for different samplerates and formats to the settings the hardware is set up to use. Every program that use ALSA for output will read the above file, but you need to restart a program for changes to take effect.

    If you enjoy audio production I’m sure you’ll find some good use for Jack, but for audio mixing all you need is to use an ALSA dmix pcm for output.

    A solution I’ve used for the glibc problem, is to build on an older distribution in a chroot. There is also this project which might be of use to pick a specific version of glibc. The project README also explain how to do it manually.

    As for distribution, I prefer something like makeself.sh, that installs to either ~/.local/ or if it is to be installed system-wide to /usr/local or /opt. The concept is just a small shell script appended with a compressed archive, it is easy to modify and even create by hand using standard tools like cat. This is a method widely used by native Linux games.
